Figure 14.1
The figure shows a wave.
-The wave from Fig. 14.1 is moving at a speed of 5 cm/s. If L1 = 6 cm and L2 = 5 cm, which wave equation describes the wave?
A) y(x, t) = (6 cm) sin[(6.28 s-1) t - (1.05 cm-1) x) ]
B) y(x, t) = (3 cm) sin[(12.6 s-1) t - (0.63 cm-1) x) ]
C) y(x, t) = (3 cm) sin[(6.28 s-1) t - (1.05 cm-1) x) ]
D) y(x, t) = (6 cm) sin[(3.76 s-1) t - (2.09 cm-1) x) ]
